I’ve tried several different flights on this right in January and receive it on all the times I want.
of course if I try it with the one time slot that doesn’t work for me, it allows me to book it
I frequently get this when trying to book same-day return flights for quick trips, I believe Google Flights / ITA Matrix is pricing out a round trip with a 2 stop outbound and direct return (or vice versa), and when AA tries to price it out, it doesn't get the same price since they price it with the round trip destination as the actual destination. Does this match your situation?
